Conducted by: David Ademe, Avantes Inc. Theme: Fluorescence Background/Applications: Fluorescence spectroscopy can be used in a wide range of applications, including medical research and analysis. There are a number of researchers that use a fiber-optic probe for in vivo fluorescence spectroscopy to study and test for cancerous cells. Fiber optic needle biopsy plays an important…
Read MoreFluorimeters are widely utilized for the quantitation of biological compounds in solution, with applications ranging from environmental/agricultural water monitoring to DNA sequencing. These devices measure fluorescence by exciting a sample with an integrated light source and collecting the emitted light using either filtered detectors or embedded spectrometers. Historically laboratory fluorimeters utilized spectrometers due to their…
Read MoreNow Available! Our new Avalight-HPLED-285 is here! With a limited wavelength range, this new light source is ideal for fluorescence measurements. Due to the absence of emitted light in the fluorescence range, the fluorescence effect can easily be detected. High powered and compact, this new light source version was made for more demanding applications. Benefits…
Read MoreA benchtop fluorimeter system provides for the ability to scan across wavelengths of excitation in order to find optimal excitation and emission combinations for fluorescent samples. A common limitation of fiber optic spectroscopy systems is that they typically only allow for isolating excitation wavelengths one at a time using bandpass or other optical filters. Fluorescence…
Read MoreAbsorption and reflection spectra can reveal the unique properties of many different types of materials and samples. This includes biological samples and plant life. This can range from leaf’s, flower petals, grass and lichen. The optical properties of lichens have been traditionally explored in the context of geological mapping where the encrustation of lichens on…
